When to File: REP Certification at the Commission generally takes 60-90 days. Upon approval of REP certification, applicants will be ordered to provide proof that they have completed the testing of their electronic interface system prior to serving customers. Since ERCOT generally has three testing periods per year, it is important to coordinate the testing dates with the REP's business plan.
